, 2010 非耕地系数反映了田间耕地与非耕地的分布情况,它的意义在于有助于获得较为准确的耕地面积。以影响非耕地系数的因素为指标对农区进行类型区划分是利用非耕地系数获取准确耕地面积的前提。首先以干旱区典型绿洲为研究区采用灰色关联方法探讨影响非耕地系数的主要因素,使用层次分析法综合影响非耕地系数的主要因素,并采用累计平方根法研究各个类型区分界点的确定。研究结果表明:影响非耕地系数的主要因素有土地利用的斑块破碎度、水网密度、农业人口密度、人均农业生产值等。将它们作为类型区划分的指标,并采用最优分层理论将类型区数目确定为8。

, 2007 本文采用分形理论的随机聚集方法和关联维数测算方法,并借助社会统计学软件spss12.0对吐鲁番地区旅游景区(点)系统的空间结构进行了研究,发现其景区(点)系统类似于有限扩散集团凝聚模型,具有分形结构。吐鲁番景点分布较集中且易形成线路组合,各景点在空间结构上的向心性作用有强弱之分,从系统的聚集中心向四周景点密度是衰减的。并据此提出了吐鲁番地区旅游景区(点 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT This study systematically investigates the creep behavior of an Al19Co21Fe20Ni40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce a heterostructure consisting of alternating lamellar and equiaxed regions.
